ok i have found my saris manor house to be i think eqivalint to a t2 human house but takes up more room then a t3 human house...also is vastly harder to make....i belive that the large old buildings (also useually have 2 levels) should be better then the new buildings(teird houses/guildhouses)of equal size (not includeing silo's) I belive it would actually improve builder economy as well
